Application filed June 26, 191'?,

4 fo aZZ whom t may concern Be it known that lf, JAMES FERDINAND GnooMROBERTS, subject of the King of Great Britaiin. residing at l5 Hollandstreet, lVellington, New Zealand, have invented a new and usefulImprovement in Cooking Apparatus; and I do hereby declare thefollowingto be a full, clear, and exact description of the same.A

This invention relates to an improved con-` struction of that class ofapparatus designed for the cooking of foods 1n large A(puantities andespecially for military, restaurant and public institution purposes andconsisting generally in a number of cooking chambers or ovens andanarrangement of flues whereby the heatfrom a fire may be distributedthrough Vsuch chambers or ovens.

more effective distribution of the heat and a more convenient andcompact grouping of the chambers and ovens, are obtained.

rThe invention is illustrated in the accompanying drawings, in which :e

Figure l is a front end elevation of the apparatus.

Fig. 2 is a back end elevation thereof.

Fig. 3 is a side elevation.

Fig. 4f is a cross sectional elevation taken through the oven chambers.

Fig. 5 is a plan of the apparatus.

Fig. 6 a sectional plan taken on the line 6-6 of Fig. 2.

Fig. 7 a sectional plan taken on the line 7-7 of Fig. 2.

Fig. 8 a vertical section of a portion of the apparatus. p

According hereto the apparatus is formed with a casing A of suitablematerial and size, and if required with insulated walls. The casingrests upon a suitable bottom plate A and is covered by a top plate A2.rlfhe space inclosed by the casing is divided into three main divisions,such divisions consisting in a furnace B situated in one front corner7 acooking chamber C at the rear end of the casing behind the furnace, andan oven division extending from front By this y l Patented Nov.. 27,fQJl't'. Serial. No. 177,136.

to back alongside the other two divisions. These several divisions aresuitably divided from one another bymeans of plates eX- tendingvertically in the casing, these plates being secured to the casing in amanner well known in the art.

The furnace space B is provided with a grate B and an ashpit below thegrate, the necessary fire door B2 being provided in the casing front toallow of access to the fire.

lThe oven division is divided into a number of ovens D extending inwardrespectively from the front and back ends of the casing and arranged oneabove the other. Four of these ovens are shown in the drawings, twoopening from the front and two from the back of the casing each pairbeing arranged one above the other as shown. The ovens thus extend backto back and eachone is furnished with a door D of suitable design topermit of access to the space inclosed thereby.

The block of` ovens thus extend on one side along the side of the lirespace B. The block isso arranged within the casing as to eave a space Ebetween its top and the top of the casing, a space F between its othersideand the outside of the casing, and a space G between its bottom andthe bottom of the casing.

i Consequently there is a continuous passage fromthe furnace B alongabove the tops of the ovens. down the outside thereof and along beneaththem.

The space E above the ovens is divided by means of a baille plate E intotwo transverse divisions while the space F is also divided into two bythe vertical baiiie F eX- tending medially down it. The space G beneaththe ovens is divided. longitudinally by a number of battles G sodisposed that a zigzag course is provided to and fro in such space andfinally to an outlet at its back end leading into a due H. Thisconstruction assures that the heat from the furnace will pass over thetops of the ovens and down the outsides thereof. beingequallydistributed over both sets by the battles E and F', and will then passto and fro beneath them a number of times, before passing to the flue H.The ovens will therefore be effectually heated.

The cooking chamber C at the back corner of the casing has the space Gextending beneath it and the flue opening leading out therefrom shown in8. `Consequently this chamber will be heated by the'f'urna-ce and alsothe .heat therefrom after it has passed around the ovens. It is soformed as to be adapted to receive cooking-vessels and is furnished witha cover C that is secured thereon by mea-ns of1 the-hingedbolts c` andwing nuts 0, or by any other approved means. p

A hot water tank J may be arranged to extend along one side of thetopof'thegcasing such tank being furnished with the usual' draw'off tapsand steam vents. y

The top plate'of the casing above thefurnace' isl'forme'd with potopenings and covers K so that cooking `vessels may be placed thereon andheated as` with ordinaryV stoves f or ran-ges.

The casing -ends arerprovided with soot openings and doors Marrangedcorrespondingly with the ashl pit and flues so that the stovemaybe cleaned as required. A stove :thus constructed is adapted eithervfor stationary or-transportpurposes and may be mounted on a carriage ofsuitable design when 'used as the latter.

Ici-aim:-

'1. A cooking apparat-us comprising `in Vcombination acasmgg", lafurnace extending fin one sidethereofto the bottom of the casing; ovenchambers extending from front to back alongside said'ffurnace; saidcasing vfbeing spaced from said chambers at the top, -at theyside'opposite said furnace, and at the bottom; said spaces at the top,side and b otl"tom'of the casing extending the'full `depth of the casingfrom front toback and-being in communicationwith said furnace; avertical flue opening directly into said space at the bottom of thecasing on thesame side as ing at the top directlyfbetween'the furnacesaid'furnace, and a cooking chamber open# VVanclwthe vertical Hue, saidchamber extending` :downward tothe bottomk space.

2. A cooking apparatus comprising 1n combination a casing, a furnaceextending in one side thereof to the bottom of the casing;

u oven chambers extending fromfront to back into two approximately equalpassages; a

vertical baifle in said4 side space opposite said furnace lforming twopassages-in rsaid side space which are continuations offthe passages insaid ltop space; and baiiies `in said bottom space runningparallel tosaid furnace andi forming a single continuousltortuous passage beneaththe ovens, and a cookingchamber opening'at the top vdirectly betweenthefurnace and the vertical flue, said chamber extending downward to thebottom space immediately in the rear of said-furnace, said cookingchamber also' being above said bottom space and said flue openingVimmediatelylin the/rear ofsai'd cooking chamber.
